On March 23, 1969, Floyd C. Miller (1902-1985) is appointed by the Seattle City Council as the 46th Mayor of Seattle to fill the term of Dorm Braman (1901-1980) who resigned to join the Nixon Administration as Assistant Secretary of the U.S. Department of Transportation. Miller is the president of the City Council and announces that he will not be a candidate for mayor in the election the following November. Miller had been elected to the Seattle City Council three times and to the State Legislature seven times.

Miller's appointment was opposed by some African-American community leaders for his past votes against open housing and against fluoridation (1964), but he also supported a Fair Employment Protection Bill and was once labeled by the Municipal League as "pink" (liberal). He was elected by unanimous voice vote on the second ballot. Miller served nine months and was succeeded by Wes Uhlman (b. 1935), who was elected in November 1969.
